Well your on Predinisone..................could that be the reason your blood sugars are fluctuating, question for your endo?
I did not mean to be so generic in my answer as I dump my blood sugar when I exercise, and I am not diabletic but I have checked it many times to find it in the 74 range and I am cool, clammy and a bit dizzy. although I am ditzy on a good day. :) Are you documenting your BS with a glucometer?
I would always rather see some one running a little high on their BS than low. I usually just grab a piece or 2 of hard candy, or a fruit.
I am not familiar with your diet but I am sure your physician is.
My Dr. was not concerned re my issue.
Hugs to you.
